[Perforating pilomatrixoma in adults].
Two rare cases of perforating pilomatrixoma similar to those reported in the literature are described. Clinical examination showed in two old-women a reddish inflammatory exophytic tumor, 1 cm in diameter, with central erosive surface, with a rapid growth (3-5 months). Histologic examination showed: multiple masses of basophilic cells situated in the upper dermis making contact with the epidermis in a "follicle-like" opening; occurrence of transepithelial elimination phenomena.
